SECTION 9 — TECHNICAL DATA
Mains supply (L1, L2, L3):
Supply voltage: 200-240 V ±10%
Supply voltage: 380-500 V ±10%
Supply voltage: 525-690 V ±10%
Mains voltage low / mains drop-out: During low mains voltage or a mains drop-out, the 302 continues until the
intermediate circuit voltage drops below the minimum stop level, which corresponds typically to 15% below the 302's lowest
rated supply voltage. Power-up and full torque cannot be expected at mains voltage lower than 10% below the 302's lowest
rated supply voltage.
Supply frequency: 50/60 Hz ±5%
Max. imbalance temporary between mains phases 3.0 % of rated supply voltage
True Power Factor (λ) ≥ 0.9 nominal at rated load
Displacement Power Factor (cos ϕ) near unity (> 0.98)
Switching on input supply L1, L2, L3 (power-ups) ≤ 7.5 kW maximum 2 times/min.
Switching on input supply L1, L2, L3 (power-ups) 11-75 kW maximum 1 time/min.
Switching on input supply L1, L2, L3 (power-ups) ≥ 90 kW maximum 1 time/2 min.
